The Research Of ZMJ ERP Operations Planning Method Based On The Thinking Of OPT

In recent years, MRP as the core enterprise resource planning system (ERP) in China's enterprises have been better promotion and application. ERP system will divide production plan into the main production plan, material requirements plan, workshops operative plan, and through the thick and thin plan of ability to adjust production plan and material requirements plan. However, the material requirements plan generated by the proposed workshops operative plan is issued to the production workshops according to the working center, when the number of workshop equipment and personnel is large, in particular, the working center is composed of more than one equipment that have same working capacity, in the case of so many types of spare part and working procedure, the job scheduling of workshop is quite difficult. And the optimized production technology (optimized production technology, OPT) with its guiding ideology focus on priority to resolve the main contradiction is particularly applicable to the productive plan and control of small-volume productive enterprise. So how to combine the respective expertise of OPT and ERP, apply OPT thoughts to the ERP application programming operations, thereby enhancing the effectiveness of operative plans, is a practical and significant research work.This paper relies on ZMJ enterprises in the production-based programming, made the solution of the basis of the MRP with OPT thinking, identify the key impact and key processes and procedures on delivery to address bottleneck processes for the major contradictions, non - Key process to take a approach of first "push" then "pull", as production management method of a large heavy enterprise mainly composed of single pieces and small group mixed many types of enterprise. Then take Zhangjiakou coal mine machinery limited liability company processing workshop production operative plan establishment method as an example, has discussed the ERP operations based programming based on OPT thoughts, so that the establishment of productive and operative plan of each subordinate production workshop is suitable for enterprise's production organization need under the existing environment, and promote a persistent and fast development of an enterprise.
